It is TM part of the CMOSTEK NextGenRF family, which includes a complete line of transmitters, receivers QFN16 (3X3) and transceivers. An embedded EEPROM allows the frequency, symbol rate and other features to be programmed into the device using the CMOSTEK USB Programmer and RFPDK. Alternatively, in stock 12 11 10 9 products of 315/433.92 MHz are available for GND 8 XIN 13 immediate demands with no need of EEPROM RFIN 7 XOUT 14 programming. W hen the CMT2210A is always on, it GND 15 6 CLKO consumes only 3.8 mA current while achieving -114 VDD 5 DOUT 16 dBm receiving sensitivity. It consumes even less 1 2 3 4 power when working in duty-cycle operation mode via the built-in sleep timer. The CMT2210A receiver together with the CMT211x transmitter enables an CMT2210A Top View ultra low cost RF link.
